Specification of Letters Patent.

Patented Oct. 22, 1907 Application filed December28, 1906. Serial No. 293,643.

To all whomllt't may concern:

Be it known that I, EDWARD TnoMrsoN WILLIAMs, a citizen of the United States, residing at New York, in the county 01' N ew York and State of New York, have invented a new and useful CarpetCleaner, of which the iollowingis a specification. I

This invention relates to carpet cleaners.

The object of the invention is to provide a simple and novel apparatus adapted for cleaning carpets upon a floor, inwhich dust and debris shall in a'ieasible manher be loosened and carried ofi without permitting any.

escape beyond the implement and thus into the room.

A further object is to adapt the apparatus to operate as a combined pressure and suction cleaner, or as a suction cleaner alone I,

A further ob ect is to provide a novel means to control the suction within the suction chamber, whereby between the carpet or floor and the cleaner.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a carpet cleaner, as willbe hereinafter fully described and' claimed.

In the accompanying drawings forming a part of this specification, and in which like characters of reference indicate coriesponding parts: Figure 1 is a view in plan of the apparatus. Fig. 2 is a view in side elevation, partly in section, thereof.

The suction chamber is triangular in form, and consists of two nested pyrmnidal members, an inner member l and an outer member 2, the two members being suitably connected together and held properly spaced apart by webs 3, of which there areshown in this instance throe, although this number may be increased if found necessary or desirable and still be within the scope of the invention, the object for making the chamber triangular as shown, being to facilitate getting into and cleaning corners of a room. The outer member is provided with an inward extending marginal flange 4,

which is spaced a suilicicnt distance from the margin,

of the inner member to form a suction slot 5, through which the debris passes to the suction outtake pipe presently to be described. Thc. outer member is provided with a boss 6 through the top of which projects and is rigidly secured the pipe 7 of the air blast system,

the lower end of which carries a plurality of branches 8,

'other end of which is suitably connected with a pipe 12 that is combined with the "14 of the implement, which constitutes a suction pipe, by clamps or I bands 15. The pipe 13 connects witha suitable source of air under pressure, or with blast mechanism so that the air that escapes through the orifices in the branch pipes 8 will operate to stir up the debris or dust in the carpet, thus facilitating its removal. The pipe 13 carries a valve casing 16 in which is mounted a valve of any preferred construction, the stem of which is connected with a handle 17 iulcrumed at 18 on the casing. This valve is so constructed that it will automatically close when the hand of the operator is removed, the construction being the same as a self closing water faucet valve in common use, if desired.

carries a threaded coupling 21 that engages a threaded orifice in the side of the boss 6, the object of this arrangemcnt being to permit the handle freely to move through the arc of a circle in manipulating the apparatus.

The free end of the handle carries a hand hold 22 adjacent to which is a coupling 23 that is engaged by a flexible pipe 24 leading to a place of discharge. The handle carries at its lower end a'yoke 25 the arms of which are pivoted between ears 26 carried by the outer 'member 2, and this arrangement will permit of the apparatus being pushed or pulled over a floor in the usual manner.

The inner member 1 is provided at its upper portion orifice 27 provided for this purpose being of greater diameter than the pipe in order that a large part of the dirt raised by the air blast will pass off through it. The underside of the rear flange is provided with a series of transverse slots 28 and with a longitudinal slot 29, and in the latter slot is arranged a shutter 30 which is engaged by three screws 31 and by which the shutter may be raised or lowered thus to maintain thepartial vacuum in the chamber sufficiently low to prevent undue friction between the floor and the cleaner, it being seen that by depressing the shutter that the supply of air will be diminished, and by raising it will be increased. This is a feature of importance, as it materially facilitates the operation of the apparatus.

As stated, the apparatus may be used either as a simple suction system, by cutting off the supply of air irom'the blast pipe, or as a double system of air blast and suction as shown.

. In use of "the apparatus, where both systems are employed, the handle 17 will be manipulated to open the valve, to permit air to be forced through the pipes 8 and on to the floor, thus loosening and stirring up mechanism connecting the pipe 24 is operated, and the dust anddi'rt loosened are drawn out in part through the suction slot 5 and in' part through the orifice 27. and pass to the pipe 20, handle 14 and pipe 24 to the with a boss through which the pipe 7 projects, thethe dust and debris; At the samev time the suctionplaceof deposit. Of course, as will be obvious steam may be supplied through the jet pipes 8 in lieu of air.

The apparatus herein described while simple in character will be found thoroughly eiiicient forthe purposes designed andvwill in a ready, rapid and thorough manner clean carpets of dust and other debris.

I claimt- 1. A carpet cleaner comprising a pair of-hollow mem--. bers placed one within the other and spaced apart to provide a suction chamber but with their lower edges in close proximity to form an inlet slit, a suction conduit communicatingwith said. suction chamber, and an adjustable shutter on the outer member to regulate the partial vacuum within thechamber. v

2. A carpet cleaner comprising a pair of hollow nested pyramidal members connected together but separated by spacing webs to produce a'suction chamber, the peripheral edgesof saidmembersibeing in closeproximityand-formingn continuous inlet slot,.and a suction conduit comma, niatlng with said suction chamber.

3. A carpet cleaner comprising a pair of hollow members having open bases and arranged one over the other with rat chamber-between .them which communicates-with the hollow oi. the innenmember, a suction conduit communicating with the upper end of the said chamber to produce a suction therethrou'gh, a conduit extending through the'members and terminating adjacent thebase of the inner.member,.a,.plurality of tubular arms communicating:

with the;said tube and having'downwardly discharging;

perforations, and an air supply pipe connected with they said second conduit.

4. A carpet cleaner comprising a pair of nested membersspaced apart, a suction conduit communicating with the space between the .members, r and a controllable means for admitting atmospheric .air :to the said space, the same comprisinga plurality ofdnwardlyextending conduits ar despot ranged on the bottom surface of one of the mcmbeis along one side thereof, an adjustable shutter for the said conduits for controlling the supply of air thereto, and devices at the ends of the shutter for raising and lowering the same.

5. A carpet cleaner comprising a suction chamber consisting of a pair of nested triangular members spaced apart. one face of the outer member being provided with slots. having open sides presented to the surface to be cleaned, an adjustable shutter intersecting: the slots. and suction mechanism communicating with the space between the members.

' 6. A carpet cleaner comprising a pair of hollow pyramidal triangular members arranged to form :1 space be tween them, a suction conduit connected with the said space, a blast mechanism housed within the hollow of the inner member, and means for controlling the blast, there being communication at the apex of the-inner member between the hollow of the inner member and the space between the members. 1

7. .ina carpet cleaner, a structure comprising two hollow pyramidal members connected together and nested with a space between them to provide a suction chamber and slightly separated at their lower edges in form a suction inlet, the edge of the outer member extending be low the edge of the inner member, a suction pipe connected to said outer member and communicating with the suction chamber, and an adjustable gate applied to the bottom of said outer member to regulate the iuiiow of air into said chamber.

In testimony that I claim the foregoing;' as my own, I have hereto aflixed my si znaturein the presence of two witnesses.
